SLEM 5 must not disable syscall auditing.

Rule version SLEM-05-654245 · STIG v1 · 2026-08-20

Discussion

By default, SLEM 5 includes the "-a task,never" audit rule as a default. This rule suppresses syscall auditing for all tasks started with this rule in effect. Because the audit daemon processes the "audit.rules" file from the top down, this rule supersedes all other defined syscall rules; therefore no syscall auditing can take place on the operating system.

Check

Verify syscall auditing has not been disabled with the following command:

     > sudo auditctl -l | grep -i "a task,never"

If any results are returned, this is a finding.

Verify the default rule "-a task,never" is not statically defined:

     > grep -rv "^#" /etc/audit/rules.d/ | grep -i "a task,never"

If any results are returned, this is a finding.

Fix

Remove the "-a task,never" rule from the /etc/audit/rules.d/audit.rules file.

The audit daemon must be restarted for the changes to take effect.

     > sudo systemctl restart auditd.service
